- Application filed December To all whom it may oo'ncern:

Be it known that I, ALQVINVJ. NASH; a citizen of the United stateix'reslding at lameda and new and useful Improvements in Spring Hubs; and I do hereby declare the follow: iug 'to' be a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to .vehicle wheels andquore particularly to the hub structure which in the present instance is yieldableto neutralize shock and .vibration' and thereby minimize the wear and tear on the vehicle,-

motor and adjuncti've parts besides adding -to the comfort of the passenger or occupant of the vehicle. p

Other objects and advantages will be apparent and suggest themselves the nature of the invention is understood.

Whilethe drawings illustrate an embodiment of the invention it is to be understood that in ads ting the same to meet diffGI'OHt COUdltIODS and requirements, various changes in the form; proportion and minor details of construction may beresortedto provided they fall within the spirit 'and sco e of the invention.

eferring to the accompanying drawings forming a part of the application Figure 1 is a. side view of a vehicle wheel embodying" the invention, a

Figure 2 is an enlarged side view of the hub portion of broken away, v. v

Figure 3 is a transverse sectional view of the hub portion,

Figure 5 is a detail-perspective view of one of the springspokes, and

F igure'G is a view similar to Figure 3 of a modification.

Corresponding and like-parts are referred to in t-he following description and designated in theiseveral views of the drawings by like reference characters.

- The wheel illustrated is of the disk typo and the disk -l' may be flat or straight, asindicated most-clearlyv in igure 3, o'r waved' .as shown most clearly at .1 in Figure 6.

opening with parallel spaced elements 3 and 4 which have adjustable connection The elements 3 and 4 are of annular formation and the one preferably is separate and bolted or otherwise attached to the disk. The hub comprises a sleeve 5 and may be or any preferred construction to receive the axle. arm (Send the usual ball- 7 and IS. The hub also includes and the plate 9 being separate and secured to the plate 10 by.=means of bolts ,11. Each of thh plates 9 and.10 is formed in its outer portion and upon its inner face with annular grooves or channels the one receiving a packing 12 of felt or other analogous ma terial and the other a wear ring 13 preferably of steel. The elcngentszii and 4 are rewired between the outer portions of theplates 9 and 10 and obtain aclose-fit ag inst the inner faces thereof. Spring spoke 14 are interposed between the hub and disk of the -v'vhecl and areconnected at opposite ends thereto. 'The z'spokes are fiat ,and curved throughout their length,- being preferably of-ogee' form in edge view. An

eye 15 is provided at the outer end of each of the spokes to receive a rivet 16 or like "fastening, whereby it is connectedto the outer portion of; the elements 3 and 4. A pintle enlargement IZ is formedat the inner end of each of the spokes and is received in an opening 18 formedin-a'retainer 19 which -is slipped upod' thofsleeve 5- and confined- :bet-ween amine .9 .'and 10. Slots 20 extend outwa flfifoni; the openin'gs'IS and are eurveditoeorrs "end with the'cur-vature of the inner englsyothe spokes 14. By having'the-slo 20:11am outwardly, provision is had. for} v mife'dplay between the inner ends of 's'pokes 14 and the retainer or holderlQ, thereby preventing the crystallizwould occur if the atter were rigidly connected to the holder 19. The openin s 18 and slo'ts20 exten'dth'rough oppos te sides of the holder 19 and'are' closed at opposite sides by means of. rings 21 which retain the spokes in and the br'e'akin .of'th'e spokes which let inplace The spokes 14 are of a width to fit suugl) between thezelemen'ts 3 and 4 and the'retainer rings 21. The sleeve 5 is formed 'with a Tlib'22 which is disposed to come between the side plates 9 and 10 and enter grooves 23 formed in the walls of the central opening of the holder 19 and' also of rings 21, whereby the latter are prevented fronr rotary. movement about the sleeve 5. The bolts ll pass through registerin'g openings formed in the holder 19 and rings'21. It is observed that the'spokes 14 are completely housed by 'the' side plates 9 and 10 and the spaced annular elements 3-and 4 provided at the inner edge of the disk and are thereby protected and this'housing may be supplied with a suitable lubricant'where by to minimize the friction of the moving parts, the packing 12 serving to prevent waste of the lubricant and to exclude dust and dirt and prevent -the same entering the housing. 'The wear is sustained and resisted by means of the rings 13. \Vhen the u plate. 9 is removed, the disk and attached spokes may be. readily removed or placed in position as required, and by having the openings 18 and slots 20 extend through opposite sides of the holder-19. the inner ends of the spokes may be readily fitted to or disconnected frem'the holder. It will thus be understood that the parts may be readily assembled and any disabled spoke may be easily and quicklvreplaced.

What is claimed 15:

-1."In a wheel hub structure side plates spaced apart and having annular grooves in the outer portion of their inner faces,

a. packing in the outermost groove, a'wear ring in the next groove, spaced elements fitting snugly within the'outer portions of saidside plates and forming the inner portion of the-outer part of the wheel, and

spring spokes connecting the outer portion 40 of the wheel with the hub and being dis-' posed between the side plates and spaced elements. v

2. A wheel hub structure comprisinga sleeve; spaced side. plates carried by the ,45

sleeve, the oueformiri'g a part thereof; a holder on the sleeve, a-disk comprising spaced elements obtaining a snugfit between the outeuportions of the side:.plates, and

spring; spi ikcs havi-ng their outer ends dis pos'ed between the spaced elements and connected thereto and having their inuer'euds connected to the said holder and-arranged bet ween the said side plates.
